Marx on Socialism

All Marx' titanic work and all his thought were directed toward providing a scientific basis for the historical necessity of the proletarian revolution and the socialist transformation of society. Marx deduced the inevitability of the change to socialism entirely from the economic law of movement of capitalism and from an analysis of contradictions inherent in capitalism. For just this reason he considered that it was completely unnecessary to write all sorts of formulas for the new society which had so much attraction for the representatives of pre-Marxist social systems.
